CONIONTIS ELLIPTICA Casey. 



Specimen No. 10018, Univ. Calif. Col. Invert. Palae. Asphalt beds at 

 Rosemary, near Los Angeles. 



The thorax and elytra of this species are present in recogniz- 

 able condition. Elliptica and robusta are very closely related 

 and some put them together. I was advised to do this, but on 

 comparing the two I find sufficient difference to separate them. 

 This form is more elongate; flatter; and the punctation and 

 striation not so evident. 



Eleodes acuticauda LeConte. 



PI. 15, fig. 7; PI. 16, figs. 16, 18, and 21. 



Specimens No. 10019, a, b, c. <l, Univ. Calif. Col. Invert. Palae. Asphalt 

 beds at Rosemary, near Los Angeles. 



These all belong to the typical form of this species. There is 

 some variation, but there is a greater variation in the living forms. 

 The species of this genus like that of Coniontis hide in dark 

 places, under boards, in rubbish and even in squirrel holes during 

 the daytime, and come out to forage in the evening after sunset. 

 So their presence in the tar springs can be easily accounted for 

 on the assumption that they made a misstep. 



Eleodes acuticauda LeConte. 



Forma punctata. 



PI. 15, fig. 2; PI. 16, fig. 15. 



Specimen No. 10020, a, b, Univ. Calif. Col. Invert. Palae. Asphalt beds 

 at Rosemary, near Los Angeles. 



This very punctate form is easily recognized and the speci- 

 mens are in a fair state of preservation. 



Eleodes behrii, n. sp. 



PI. 15, figs. 3 and 4. 



Type specimen No. 10023, Univ. Calif. Col. Invert. Palae. Asphalt beds 

 at Rosemary, near Los Angeles. 



A perfect specimen — with the exception of the missing head. 

 Narrowly oval, slightly flattened dorsally, tapering and depressed
